The keeper made the revelation on his personal Twitter after the deal was completed. The 18-year old was a former Leeds Under-18 star. He was the main man for the youth team but he was not offered a pro deal by the club.

“Good luck to #lufc second year scholar goalkeeper Theo Robinson who has been told he won’t be getting a pro contract and is free to leave,” Lufcyouth academy posted early last month.

Man United decided to seize the opportunity to offer the youngster a deal. He was undergoing trial at Old Trafford whilst on his second year of a two-year Elland Road scholarship.

Richardson has since changed his allegiance from Leeds to United on his public profiles. He was named in the 2-2 draw against Manchester City in the Premier League Under-18. He also featured in another match for the famous United youth team: he played the full game against Chelsea at Cobham though United lost 4-3.

The Linclon-born shot stopper shakes off the failure of getting a pro deal at Leeds as he moves from Yorkshire to Greater Manchester. The Leeds senior side are hoping to get their acts together before the season ends. They lost to Reading in the last game but they are set to face Brentford on Tuesday.

Leeds have garnered 69 points after 39 games and it seems they are keen on finishing in the top six come May.

United are in the market for a new keeper for the senior team amid a renewed interest by Real Madrid for David De Gea. If De Gea exits this summer, United would have to get one of the top keepers on its shortlist, but they would not come easy.
